[RFC PATCH] acpi/pci: mcfg: add quirk for Marvell Armada8k

by Ard Biesheuvel

This implements a quirk for the Marvell Armada80x0 running in ACPI mode, in which case the config space configuration is not 100% ECAM compatible. The issue with this SoC is that it only consists of a host bridge, and all type 0 configuration cycles are forwarded to the peer (i.e., the device in the slot), which will therefore appear at all device slots on bus 0. This can be fixed by reducing the IATU window size for bus 0, but due to CX_ATU_MIN_REGION_SIZE == 64KB (which is a synthesis-time configuration parameter of the IP block) the window producing type 0 config cycles will always produce two copies of the peer device. So add a quirk that specifies a config space accessor override, and override config space accesses to devices on bus 0 other than device 0.

[PATCH v24 00/11] acpi, clocksource: add GTDT driver and GTDT support in arm_arch_timer

by fu.wei＠linaro.org

From: Fu Wei <fu.wei(a)linaro.org> This patchset: (1)Preparation for adding GTDT support in arm_arch_timer: 1. Introduce a MMIO CNTFRQ helper. 2. separate out device-tree code from arch_timer_detect_rate 3. replace arch_timer_detect_rate with arch_timer_of_configure_rate 4. Refactor arch_timer_needs_probing, and move it into DT init call 5. Introduce some new structs and refactor the MMIO timer init code for reusing some common code. (2)Introduce ACPI GTDT parser: drivers/acpi/arm64/gtdt.c Parse all kinds of timer in GTDT table of ACPI:arch timer, memory-mapped timer and SBSA Generic Watchdog timer.

[PATCH v22 00/11] acpi, clocksource: add GTDT driver and GTDT support in arm_arch_timer

by fu.wei＠linaro.org

From: Fu Wei <fu.wei(a)linaro.org> This patchset: (1)Preparation for adding GTDT support in arm_arch_timer: 1. Introduce a wrapper function to get the frequency from mmio. 2. separate out device-tree code from arch_timer_detect_rate 3. remove arch_timer_detect_rate use arch_timer_*get_cntfrq directly 4. Refactor arch_timer_needs_probing, and move it into DT init call 5. Introduce some new structs and refactor the MMIO timer init code for reusing some common code. (2)Introduce ACPI GTDT parser: drivers/acpi/arm64/acpi_gtdt.c Parse all kinds of timer in GTDT table of ACPI:arch timer, memory-mapped timer and SBSA Generic Watchdog timer. This driver can help to simplify all the relevant timer drivers, and separate all the ACPI GTDT knowledge from them. (3)Simplify ACPI code for arm_arch_timer (4)Add GTDT support for ARM memory-mapped timer. This patchset has been tested on the following platforms with ACPI enabled: (1)ARM Foundation v8 model Changelog: v22: https://lkml.org/lkml/2017/3/21/ Rebase to git://git.kernel.org/pub/scm/linux/kernel/git/mark/linux.git arch-timer/cleanup Only Introduce arch_timer_mem_get_cntfrq to get the frequency from mmio. Merged patch 2,3(about arch_timer_detect_rate). Keep arch_timer_rate, do NOT split it for different types of timer. Improve memory-mapped timer support by comments and variable name: data-->timer_mem frame-->gtdt_frame Delete zero check for SBSA watchdog irq. Skip secure SBSA watchdog in GTDT driver. Delete Kconfig modification for SBSA watchdog driver. Delete no_irq, using nr_res instead. v21: https://lkml.org/lkml/2017/2/6/734 Introduce two functions to get the frequency from mmio and sysreg. Remove arch_timer_detect_rate use arch_timer_get_*_freq directly Split arch_timer_rate for different types of timer. Skip secure timer frame in GTDT driver.

[PATCH v2] EFI: fix build for AARCH64

by Leif Lindholm

AARCH64 build was left out of initial version, so add to .dsc and set ACPI_MACHINE_WIDTH correctly. Also, acpidump.inf specified explicit per-architecture (but identical) CFLAGS.

kernelci.org: infrastructure woes, reducing number of trees

by Kevin Hilman

If you're on the To: line, you have a kernel tree currently being build/boot tested by kernelCI.org that will be disabled (hopefully, temporarily.) Our infrastructure (graciously hosted by Linaro) is having several problems, and is not currently scaling well as we've been adding trees. These issues have been causing a variety of problems, but mainly resulting lots of false failures and generally low quality and usefulness of the reporting. Until we have the time and resources to address these growing pains (kernel CI is currently all-volunteer, spare-time only), we've decided to reduce the number of trees we build to: mainline, linux-next, arm-soc, and stable. This will reduce load and (hopefully) increase the quality of the remaining upstream-focused build/boot results until we have the resources (both time and humans) to address the current problems and make things scalable to a large number of trees. Sorry for the inconvenience, Kevin (on behalf of the core kernel CI team of myself and the Linaro crew: Tyler Baker, Milo Casagrande, Mark Brown and Matt Hart.)

[PATCH v2] PCI: Add information about describing PCI in ACPI

by Bjorn Helgaas

Here's another stab at this writeup. I'd appreciate any comments! Changes from v1 to v2: - Consumer/Producer is defined for Extended Address Space descriptors; should be ignored for QWord/DWord/Word Address Space descriptors - New arches may use Extended Address Space descriptors in PNP0A03 for bridge registers, including ECAM (if the arch adds support for this) - Add more details about MCFG and _CBA (Lv's suggestion) - Incorporate Rafael's suggestions --- Bjorn Helgaas (1): PCI: Add information about describing PCI in ACPI Documentation/PCI/00-INDEX | 2 Documentation/PCI/acpi-info.txt | 180 +++++++++++++++++++++++++++++++++++++++ 2 files changed, 182 insertions(+) create mode 100644 Documentation/PCI/acpi-info.txt

[PATCH v20 00/17] acpi, clocksource: add GTDT driver and GTDT support in arm_arch_timer

by fu.wei＠linaro.org

From: Fu Wei <fu.wei(a)linaro.org> This patchset: (1)Preparation for adding GTDT support in arm_arch_timer: 1. Clean up printk() usage 2. Rename the type macros 3. Rename the PPI enum & enum values 4. Move the type macro and PPI enum into the header file 5. Add new enum for SPIs 6. Rework PPI determination; 7. Rework counter frequency detection; 8. Refactor arch_timer_needs_probing, move it into DT init call 9. Introduce some new structs and refactor the MMIO timer init code for reusing some common code. (2)Introduce ACPI GTDT parser: drivers/acpi/arm64/acpi_gtdt.c Parse all kinds of timer in GTDT table of ACPI:arch timer, memory-mapped timer and SBSA Generic Watchdog timer. This driver can help to simplify all the relevant timer drivers, and separate all the ACPI GTDT knowledge from them. (3)Simplify ACPI code for arm_arch_timer (4)Add GTDT support for ARM memory-mapped timer. This patchset has been tested on the following platforms with ACPI enabled: (1)ARM Foundation v8 model Changelog: v20: https://lkml.org/lkml/2017/1/18/ Reorder the first 4 patches and split the 4th patches.

[PATCH v18 00/15] acpi, clocksource: add GTDT driver and GTDT support in arm_arch_timer

by fu.wei＠linaro.org

From: Fu Wei <fu.wei(a)linaro.org> This patchset: (1)Preparation for adding GTDT support in arm_arch_timer: 1. Move some enums and marcos to header file; 2. Add a new enum for spi type; 3. Improve printk relevant code; 4. Rename some enums and defines; 5. Rework PPI determination; 6. Rework counter frequency detection; 7. Refactor arch_timer_needs_probing, move it into DT init call 8. Introduce some new structs and refactor the MMIO timer init code for reusing some common code. (2)Introduce ACPI GTDT parser: drivers/acpi/arm64/acpi_gtdt.c Parse all kinds of timer in GTDT table of ACPI:arch timer, memory-mapped timer and SBSA Generic Watchdog timer.

[PATCH] EFI: fix build for AARCH64

by Leif Lindholm

AARCH64 build was left out of initial version, so add to .dsc and set ACPI_MACHINE_WIDTH correctly. Also, acpidump.inf specified explicit per-architecture (but identical) CFLAGS. Rather than duplicating this further, use the same setting for all architectures until there is actually a need to diverge. Also update README to make it obvious AArch64 is supported.

ACPI namespace details for ARM64

by Bjorn Helgaas

Hi all, We've been working through the details of getting ACPI to work on arm64, and there have been lots of questions about what this means for PCI. I've outlined this for several people individually, but I'm going to send this separately, apart from a specific patch series, to make sure we're all on the same page. Please correct my errors and misunderstandings. Bjorn The basic requirement is that the ACPI namespace should describe *everything* that consumes address space unless there's another standard way for the OS to find it [1, 2]. For example, windows that are forwarded to PCI by a PCI host bridge should be described via ACPI devices, since the OS can't locate the host bridge by itself. PCI devices *below* the host bridge do not need to be described via ACPI, because the resources they consume are inside the host bridge windows, and the OS can discover them via the standard PCI enumeration mechanism (using config accesses to read and size the BARs). This ACPI resource description is done via _CRS methods of devices in the ACPI namespace [2]. _CRS methods are like generalized PCI BARs: the OS can read _CRS and figure out what resource is being consumed even if it doesn't have a driver for the device [3]. That's important because it means an old OS can work correctly even on a system with new devices unknown to the OS. The new devices won't do anything, but the OS can at least make sure no resources conflict with them. Static tables like MCFG, HPET, ECDT, etc., are *not* mechanisms for reserving address space! The static tables are for things the OS needs to know early in boot, before it can parse the ACPI namespace. If a new table is defined, an old OS needs to operate correctly even though it ignores the table. _CRS allows that because it is generic and understood by the old OS; a static table does not. If the OS is expected to manage an ACPI device, that device will have a specific _HID/_CID that tells the OS what driver to bind to it, and the _CRS tells the OS and the driver where the device's registers are. PNP0C02 "motherboard" devices are basically a catch-all. There's no programming model for them other than "don't use these resources for anything else." So any address space that is (1) not claimed by some other ACPI device and (2) should not be assigned by the OS to something else, should be claimed by a PNP0C02 _CRS method. PCI host bridges are PNP0A03 or PNP0A08 devices. Their _CRS should describe all the address space they consume. In principle, this would be all the windows they forward down to the PCI bus, as well as the bridge registers themselves. The bridge registers include things like secondary/subordinate bus registers that determine the bus range below the bridge, window registers that describe the apertures, etc. These are all device-specific, non-architected things, so the only way a PNP0A03/PNP0A08 driver can manage them is via _PRS/_CRS/_SRS, which contain the device-specific details. These bridge registers also include ECAM space, since it is consumed by the bridge. ACPI defined a Producer/Consumer bit that was intended to distinguish the bridge apertures from the bridge registers [4, 5]. However, BIOSes didn't use that bit correctly, and the result is that OSes have to assume that everything in a PCI host bridge _CRS is a window. That leaves no way to describe the bridge registers in the PNP0A03/PNP0A08 device itself. The workaround is to describe the bridge registers (including ECAM space) in PNP0C02 catch-all devices [6]. With the exception of ECAM, the bridge register space is device-specific anyway, so the generic PNP0A03/PNP0A08 driver (pci_root.c) has no need to know about it. For ECAM, pci_root.c learns about the space from either MCFG or the _CBA method. Note that the PCIe spec actually does require ECAM unless there's a standard firmware interface for config access, e.g., the ia64 SAL interface [7]. One reason is that we want a generic host bridge driver (pci_root.c), and a generic driver requires a generic way to access config space. [1] ACPI 6.0, sec 6.1: For any device that is on a non-enumerable type of bus (for example, an ISA bus), OSPM enumerates the devices' identifier(s) and the ACPI system firmware must supply an _HID object ... for each device to enable OSPM to do that. [2] ACPI 6.0, sec 3.7: The OS enumerates motherboard devices simply by reading through the ACPI Namespace looking for devices with hardware IDs. Each device enumerated by ACPI includes ACPI-defined objects in the ACPI Namespace that report the hardware resources the device could occupy [_PRS], an object that reports the resources that are currently used by the device [_CRS], and objects for configuring those resources [_SRS]. The information is used by the Plug and Play OS (OSPM) to configure the devices. [3] ACPI 6.0, sec 6.2: OSPM uses device configuration objects to configure hardware resources for devices enumerated via ACPI. Device configuration objects provide information about current and possible resource requirements, the relationship between shared resources, and methods for configuring hardware resources. When OSPM enumerates a device, it calls _PRS to determine the resource requirements of the device. It may also call _CRS to find the current resource settings for the device. Using this information, the Plug and Play system determines what resources the device should consume and sets those resources by calling the device’s _SRS control method. In ACPI, devices can consume resources (for example, legacy keyboards), provide resources (for example, a proprietary PCI bridge), or do both. Unless otherwise specified, resources for a device are assumed to be taken from the nearest matching resource above the device in the device hierarchy.

[PATCH V6 0/5] ECAM quirks handling for ARM64 platforms

by Tomasz Nowicki

Quirk handling relies on an idea of simple static array which contains quirk enties. Each entry consists of identification information (IDs from standard header of MCFG table) along with custom pci_ecam_ops structure and configuration space resource structure. This way it is possible find corresponding quirk entries and override pci_ecam_ops and PCI configuration space regions. As an example, the last 3 patches present quirk handling mechanism usage for ThunderX. v5 -> v6 - rebase against v4.8-rc5 - drop patch 1 form previous series - keep pci_acpi_setup_ecam_mapping() in ARM64 arch directory - move quirk code to pci_mcfg.c - restrict quirk to override pci_ecam_ops and CFG resource structure only, no init call any more - split ThunderX quirks into the smaller chunks - add ThunderX pass1.x silicon revision support v4 -> v5 - rebase against v4.8-rc1 - rework to exact MCFG OEM ID, TABLE ID, rev match - use memcmp instead of strncmp - no substring match - fix typos and dmesg message Tomasz Nowicki (5): PCI/ACPI: Extend pci_mcfg_lookup() responsibilities PCI/ACPI: Check platform specific ECAM quirks PCI: thunder-pem: Allow to probe PEM-specific register range for ACPI case PCI: thunder: Enable ACPI PCI controller for ThunderX pass2.x silicon version PCI: thunder: Enable ACPI PCI controller for ThunderX pass1.x silicon version arch/arm64/kernel/pci.c | 17 ++-- drivers/acpi/pci_mcfg.c | 168 +++++++++++++++++++++++++++++++++++- drivers/pci/host/pci-thunder-ecam.c | 2 +- drivers/pci/host/pci-thunder-pem.c | 63 +++++++++++--- include/linux/pci-acpi.h | 4 +- include/linux/pci-ecam.h | 7 ++ 6 files changed, 230 insertions(+), 31 deletions(-) -- 1.9.1

[PATCH 0/2] ACPI: Ignore Consumer/Producer for QWord/DWord/Word Address Space

by Bjorn Helgaas

Per spec, the Consumer/Producer bit is defined only for Extended Address Space descriptors and should be ignored for QWord/DWord/Word Address Space descriptors. My understanding is that this is because x86 BIOSes didn't use the bit consistently, so it couldn't be relied upon. The Extended descriptors were added later and are presumably more reliable. Linux currently looks at Consumer/Producer for all Address Space descriptors, although we don't use the result very much. The x86 and ia64 host bridge driver code doesn't use Consumer/Producer to identify windows; it assumes all descriptors are windows. We do currently use Consumer/Producer to decide whether to apply _TRA. The change in these patches is to ignore Consumer/Producer for QWord/DWord/Word, so we'll apply _TRA from Consumer descriptors where we didn't before. Per spec, that should be safe because _TRA is required to be zero for Consumer resources. If we want to describe host bridge register space and ECAM space directly in the PNP0A03 device on ARM64 (and I guess potentially even on x86 & ia64), I think we need changes like this so the arch code can use IORESOURCE_WINDOW to tell which descriptors are windows and which are registers. This is a subtle area, so please take a look and let me know what you think. These patches are based on v4.9-rc1. It's getting pretty late in the cycle, but I think we'd really like to get the ARM64 ACPI PCI story sorted out for the v4.10 merge window. --- Bjorn Helgaas (2): ACPI: Combine acpi_dev_resource_address_space() and acpi_dev_resource_ext_address_space() ACPI: Ignore Consumer/Producer for QWord/DWord/Word Address Space drivers/acpi/ioapic.c | 3 - drivers/acpi/resource.c | 130 ++++++++++++++++++---------------------- drivers/pnp/pnpacpi/rsparser.c | 3 - include/linux/acpi.h | 2 - 4 files changed, 59 insertions(+), 79 deletions(-)

For example, windows that +are forwarded to PCI by a PCI host bridge should be described via ACPI +devices, since the OS can't locate the host bridge by itself. PCI +devices *below* the host bridge do not need to be described via ACPI, +because the resources they consume are inside the host bridge windows, +and the OS can discover them via the standard PCI enumeration +mechanism (using config accesses to read and size the BARs). + +This ACPI resource description is done via _CRS methods of devices in +the ACPI namespace [2]. _CRS methods are like generalized PCI BARs: +the OS can read _CRS and figure out what resource is being consumed +even if it doesn't have a driver for the device [3]. That's important +because it means an old OS can work correctly even on a system with +new devices unknown to the OS. The new devices won't do anything, but +the OS can at least make sure no resources conflict with them. + +Static tables like MCFG, HPET, ECDT, etc., are *not* mechanisms for +reserving address space! The static tables are for things the OS +needs to know early in boot, before it can parse the ACPI namespace. +If a new table is defined, an old OS needs to operate correctly even +though it ignores the table. _CRS allows that because it is generic +and understood by the old OS; a static table does not. + +If the OS is expected to manage an ACPI device, that device will have +a specific _HID/_CID that tells the OS what driver to bind to it, and +the _CRS tells the OS and the driver where the device's registers are. + +PNP0C02 "motherboard" devices are basically a catch-all. There's no +programming model for them other than "don't use these resources for +anything else." So any address space that is (1) not claimed by some +other ACPI device and (2) should not be assigned by the OS to +something else, should be claimed by a PNP0C02 _CRS method. + +PCI host bridges are PNP0A03 or PNP0A08 devices. Their _CRS should +describe all the address space they consume. In principle, this would +be all the windows they forward down to the PCI bus, as well as the +bridge registers themselves. The bridge registers include things like +secondary/subordinate bus registers that determine the bus range below +the bridge, window registers that describe the apertures, etc. These +are all device-specific, non-architected things, so the only way a +PNP0A03/PNP0A08 driver can manage them is via _PRS/_CRS/_SRS, which +contain the device-specific details. These bridge registers also +include ECAM space, since it is consumed by the bridge. + +ACPI defined a Producer/Consumer bit that was intended to distinguish +the bridge apertures from the bridge registers [4, 5]. However, +BIOSes didn't use that bit correctly, and the result is that OSes have +to assume that everything in a PCI host bridge _CRS is a window. That +leaves no way to describe the bridge registers in the PNP0A03/PNP0A08 +device itself. + +The workaround is to describe the bridge registers (including ECAM +space) in PNP0C02 catch-all devices [6]. With the exception of ECAM, +the bridge register space is device-specific anyway, so the generic +PNP0A03/PNP0A08 driver (pci_root.c) has no need to know about it. For +ECAM, pci_root.c learns about the space from either MCFG or the _CBA +method. + +Note that the PCIe spec actually does require ECAM unless there's a +standard firmware interface for config access, e.g., the ia64 SAL +interface [7]. One reason is that we want a generic host bridge +driver (pci_root.c), and a generic driver requires a generic way to +access config space. + + +[1] ACPI 6.0, sec 6.1: + For any device that is on a non-enumerable type of bus (for + example, an ISA bus), OSPM enumerates the devices' identifier(s) + and the ACPI system firmware must supply an _HID object ... for + each device to enable OSPM to do that. + +[2] ACPI 6.0, sec 3.7: + The OS enumerates motherboard devices simply by reading through + the ACPI Namespace looking for devices with hardware IDs. + + Each device enumerated by ACPI includes ACPI-defined objects in + the ACPI Namespace that report the hardware resources the device + could occupy [_PRS], an object that reports the resources that are + currently used by the device [_CRS], and objects for configuring + those resources [_SRS]. The information is used by the Plug and + Play OS (OSPM) to configure the devices. + +[3] ACPI 6.0, sec 6.2: + OSPM uses device configuration objects to configure hardware + resources for devices enumerated via ACPI. Device configuration + objects provide information about current and possible resource + requirements, the relationship between shared resources, and + methods for configuring hardware resources. + + When OSPM enumerates a device, it calls _PRS to determine the + resource requirements of the device. It may also call _CRS to + find the current resource settings for the device. Using this + information, the Plug and Play system determines what resources + the device should consume and sets those resources by calling the + device’s _SRS control method. + + In ACPI, devices can consume resources (for example, legacy + keyboards), provide resources (for example, a proprietary PCI + bridge), or do both. Unless otherwise specified, resources for a + device are assumed to be taken from the nearest matching resource + above the device in the device hierarchy. + +[4] ACPI 6.0, sec 6.4.3.5.4: + Extended Address Space Descriptor + General Flags: Bit [0] Consumer/Producer: + 1–This device consumes this resource + 0–This device produces and consumes this resource + +[5] ACPI 6.0, sec 19.6.43: + ResourceUsage specifies whether the Memory range is consumed by + this device (ResourceConsumer) or passed on to child devices + (ResourceProducer). If nothing is specified, then + ResourceConsumer is assumed. + +[6] PCI Firmware 3.0, sec 4.1.2: + If the operating system does not natively comprehend reserving the + MMCFG region, the MMCFG region must be reserved by firmware. The + address range reported in the MCFG table or by _CBA method (see + Section 4.1.3) must be reserved by declaring a motherboard + resource. For most systems, the motherboard resource would appear + at the root of the ACPI namespace (under \_SB) in a node with a + _HID of EISAID (PNP0C02), and the resources in this case should + not be claimed in the root PCI bus’s _CRS. The resources can + optionally be returned in Int15 E820 or EFIGetMemoryMap as + reserved memory but must always be reported through ACPI as a + motherboard resource. + +[7] PCI Express 3.0, sec 7.2.2: + For systems that are PC-compatible, or that do not implement a + processor-architecture-specific firmware interface standard that + allows access to the Configuration Space, the ECAM is required as + defined in this section.

[PATCH 0/3] [v2] Add basic ACPI support to the Qualcomm Technologies EMAC driver

by Timur Tabi

This patch series adds support to the EMAC driver for extracting addresses, interrupts, and some _DSDs (properties) from ACPI. The first two patches clean up the code, and the third patch adds ACPI-specific functionality. The first patch fixes a bug with handling the platform_device for the internal PHY. This phy is treated as a separate device in both DT and ACPI, but since the platform is not released automatically when the driver unloads, managed functions like devm_ioremap_resource cannot be used. The second patch replaces of_get_mac_address with its platform-independent equivalent device_get_mac_address. The third patch parses the ACPI tables to obtain the platform_device for the primary EMAC node ("QCOM8070") and the internal phy node ("QCOM8071").

[PATCH 1/2] net: qcom/emac: do not use devm on internal phy pdev

by Timur Tabi

The platform_device returned by of_find_device_by_node() is not automatically released when the driver unprobes. Therefore, managed calls like devm_ioremap_resource() should not be used. Instead, we manually allocate the resources and then free them on driver release.

find_child_device() on ACPI node works only once

I need help getting my ACPI table parsing code to work correctly. My driver fails to find the child device in a node when the driver is unloaded and reloaded. I suspect that I'm not freeing a resource correctly. Here is my ACPI table (trimmed): Device (MAC0) { Name (_HID, "QCOM8070") Name (_UID, 0) Method (_CRS, 0x0, Serialized) { Name (RBUF, ResourceTemplate() { ... Return (RBUF) } } Device (IPHY) { Name (_HID, "QCOM8071") Method (_CRS, 0x0, Serialized) { Name (RBUF, ResourceTemplate () { ... Return (RBUF) } } So QCOM8071 is a child device for QCOM8070. The driver probes on QCOM8070 and then manually instantiates QCOM8071. static const struct acpi_device_id emac_acpi_match[] = { { .id = "QCOM8070", }, {} }; MODULE_DEVICE_TABLE(acpi, emac_acpi_match); static struct platform_driver emac_platform_driver = { .probe = emac_probe, .remove = emac_remove, .driver = { .name = "qcom-emac", .acpi_match_table = ACPI_PTR(emac_acpi_match), }, }; In emac_probe, I do this: struct device *dev; dev = device_find_child(&pdev->dev, NULL, emac_sgmii_acpi_match); adpt->sgmii_pdev = to_platform_device(dev); And here's emac_sgmii_acpi_match: > static int emac_sgmii_acpi_match(struct device *dev, void *data) > { > static const struct acpi_device_id match_table[] = { > { > .id = "QCOM8071", > }, > {} > }; > const struct acpi_device_id *id = acpi_match_device(match_table, dev); > > return !!id; > } When my driver exits, I call platform_device_unregister(adpt->sgmii_pdev); So here's the problem: the second time my driver is loaded, emac_sgmii_acpi_match() always returns false. The QCOM8071 child node no longer exists. It's apparently hidden in some way. I've been trying for several days to debug this, and I'm at my wits' end. I'm assuming that I'm not freeing the resource properly, but other than calling platform_device_unregister(), what else should I do? -- Qualcomm Datacenter Technologies, Inc. as an affiliate of Qualcomm Technologies, Inc.

[PATCH v13 0/8] acpi, clocksource: add GTDT driver and GTDT support in arm_arch_timer

by fu.wei＠linaro.org

From: Fu Wei <fu.wei(a)linaro.org> This patchset: (1)Preparation for adding GTDT support in arm_arch_timer: 1. Move some enums and marcos to header file; 2. Add a new enum for spi type; 3. Improve printk relevant code. (2)Introduce ACPI GTDT parser: drivers/acpi/arm64/acpi_gtdt.c Parse all kinds of timer in GTDT table of ACPI:arch timer, memory-mapped timer and SBSA Generic Watchdog timer.

As an example, the last patch presents quirk handling mechanism usage for ThunderX PEM driver. v4 -> v5 - rebase against v4.8-rc1 - rework to exact MCFG OEM ID, TABLE ID, rev match - use memcmp instead of strncmp - no substring match - fix typos and dmesg message Tomasz Nowicki (5): PCI: Embed pci_ecam_ops in pci_config_window structure PCI/ACPI: Move ACPI ECAM mapping to generic MCFG driver PCI: Check platform specific ECAM quirks ARM64/PCI: Start using quirks handling for ACPI based PCI host controller PCI: thunder-pem: Support quirky configuration space access for ACPI based PCI host controller arch/arm64/kernel/pci.c | 42 +---------------- drivers/acpi/pci_mcfg.c | 40 ++++++++++++++++ drivers/pci/ecam.c | 6 +-- drivers/pci/host/Makefile | 1 + drivers/pci/host/mcfg-quirks.c | 93 ++++++++++++++++++++++++++++++++++++ drivers/pci/host/mcfg-quirks.h | 24 ++++++++++ drivers/pci/host/pci-thunder-pem.c | 96 ++++++++++++++++++++++++++++++++------ include/linux/pci-acpi.h | 5 ++ include/linux/pci-ecam.h | 2 +- 9 files changed, 252 insertions(+), 57 deletions(-) create mode 100644 drivers/pci/host/mcfg-quirks.c create mode 100644 drivers/pci/host/mcfg-quirks.h -- 1.9.1

[PATCH v10 0/8] acpi, clocksource: add GTDT driver and GTDT support in arm_arch_timer

by fu.wei＠linaro.org

From: Fu Wei <fu.wei(a)linaro.org> This patchset: (1)Preparation for adding GTDT support in arm_arch_timer: 1. Move some enums and marcos to header file; 2. Add a new enum for spi type; 3. Improve printk relevant code. (2)Introduce ACPI GTDT parser: drivers/acpi/arm64/acpi_gtdt.c Parse all kinds of timer in GTDT table of ACPI:arch timer, memory-mapped timer and SBSA Generic Watchdog timer. This driver can help to simplify all the relevant timer drivers, and separate all the ACPI GTDT knowledge from them. (3)Simplify ACPI code for arm_arch_timer (4)Add GTDT support for ARM memory-mapped timer This patchset has been tested on the following platforms: (1)ARM Foundation v8 model Changelog: V10: https://lkml.org/lkml/2016/7/26/ Drop the "readq" patch. Rebase to latest Linux 4.7. V9: https://lkml.org/lkml/2016/7/25/345 Improve pr_err message in acpi gtdt driver. Update Commit message for 7/9 shorten the irq mapping function name Improve GTDT driver for memory-mapped timer v8: https://lkml.org/lkml/2016/7/19/660 Improve "pr_fmt(fmt)" definition: add "ACPI" in front of "GTDT", and also improve printk message. Simplify is_timer_block and is_watchdog. Merge acpi_gtdt_desc_init and gtdt_arch_timer_init into acpi_gtdt_init(); Delete __init in include/linux/acpi.h for GTDT API Make ARM64 select GTDT. Delete "#include <linux/module.h>" from acpi_gtdt.c Simplify GT block parse code. v7: https://lkml.org/lkml/2016/7/13/769 Move the GTDT driver to drivers/acpi/arm64 Add add the ARM64-specific ACPI Support maintainers in MAINTAINERS Merge 3 patches of GTDT parser driver. Fix the for_each_platform_timer bug. v6: https://lkml.org/lkml/2016/6/29/580 split the GTDT driver to 4 parts: basic, arch_timer, memory-mapped timer, and SBSA Generic Watchdog timer Improve driver by suggestions and example code from Daniel Lezcano v5: https://lkml.org/lkml/2016/5/24/356 Sorting out all patches, simplify the API of GTDT driver: GTDT driver just fills the data struct for arm_arch_timer driver. v4: https://lists.linaro.org/pipermail/linaro-acpi/2016-March/006667.html Delete the kvm relevant patches Separate two patches for sorting out the code for arm_arch_timer. Improve irq info export code to allow missing irq info in GTDT table. v3: https://lkml.org/lkml/2016/2/1/658 Improve GTDT driver code: (1)improve pr_* by defining pr_fmt(fmt) (2)simplify gtdt_sbsa_gwdt_init (3)improve gtdt_arch_timer_data_init, if table is NULL, it will try to get GTDT table. Move enum ppi_nr to arm_arch_timer.h, and add enum spi_nr. Add arm_arch_timer get ppi from DT and GTDT support for kvm. v2: https://lkml.org/lkml/2015/12/2/10 Rebase to latest kernel version(4.4-rc3). Fix the bug about the config problem, use CONFIG_ACPI_GTDT instead of CONFIG_ACPI in arm_arch_timer.c v1: The first upstreaming version: https://lkml.org/lkml/2015/10/28/553 Fu Wei (8): clocksource/drivers/arm_arch_timer: Move enums and defines to header file clocksource/drivers/arm_arch_timer: Add a new enum for spi type clocksource/drivers/arm_arch_timer: Improve printk relevant code acpi/arm64: Add GTDT table parse driver clocksource/drivers/arm_arch_timer: Simplify ACPI support code. acpi/arm64: Add memory-mapped timer support in GTDT driver clocksource/drivers/arm_arch_timer: Add GTDT support for memory-mapped timer acpi/arm64: Add SBSA Generic Watchdog support in GTDT driver arch/arm64/Kconfig | 1 + drivers/acpi/Kconfig | 5 + drivers/acpi/Makefile | 1 + drivers/acpi/arm64/Kconfig | 5 + drivers/acpi/arm64/Makefile | 1 + drivers/acpi/arm64/acpi_gtdt.c | 309 +++++++++++++++++++++++++++++++++++ drivers/clocksource/Kconfig | 2 +- drivers/clocksource/arm_arch_timer.c | 225 +++++++++++++++++-------- drivers/watchdog/Kconfig | 1 + include/clocksource/arm_arch_timer.h | 32 ++++ include/linux/acpi.h | 7 + 11 files changed, 518 insertions(+), 71 deletions(-) create mode 100644 drivers/acpi/arm64/Kconfig create mode 100644 drivers/acpi/arm64/Makefile create mode 100644 drivers/acpi/arm64/acpi_gtdt.c -- 2.5.5

[PATCH v12] acpi, apei, arm64: APEI initial support for aarch64.

by fu.wei＠linaro.org

From: Tomasz Nowicki <tomasz.nowicki(a)linaro.org> This commit provides APEI arch-specific bits for aarch64 Meanwhile, (1)add a new subfunction "hest_ia32_init" for "acpi_disable_cmcff" which is used by IA-32 Architecture Corrected Machine Check (CMC). (2)move HEST type (ACPI_HEST_TYPE_IA32_CORRECTED_CHECK) checking to a generic place. (3)select HAVE_ACPI_APEI when EFI and ACPI is set on ARM64, because arch_apei_get_mem_attribute is using efi_mem_attributes on ARM64.

[PATCH v9 0/9] acpi, clocksource: add GTDT driver and GTDT support in arm_arch_timer

by fu.wei＠linaro.org

From: Fu Wei <fu.wei(a)linaro.org> This patchset: (1)Preparation for adding GTDT support in arm_arch_timer: 1. Move some enums and marcos to header file; 2. Add a new enum for spi type; 3. Improve printk relevant code; 4. use readq to get 64-bit CNTVCT. (2)Introduce ACPI GTDT parser: drivers/acpi/arm64/acpi_gtdt.c Parse all kinds of timer in GTDT table of ACPI:arch timer, memory-mapped timer and SBSA Generic Watchdog timer. This driver can help to simplify all the relevant timer drivers, and separate all the ACPI GTDT knowledge from them. (3)Simplify ACPI code for arm_arch_timer (4)Add GTDT support for ARM memory-mapped timer This patchset has been tested on the following platforms: (1)ARM Foundation v8 model Changelog: V9: https://lkml.org/lkml/2016/7/25/ Improve pr_err message in acpi gtdt driver. Update Commit message for 7/9 shorten the irq mapping function name Improve GTDT driver for memory-mapped timer v8: https://lkml.org/lkml/2016/7/19/660 Improve "pr_fmt(fmt)" definition: add "ACPI" in front of "GTDT", and also improve printk message. Simplify is_timer_block and is_watchdog. Merge acpi_gtdt_desc_init and gtdt_arch_timer_init into acpi_gtdt_init(); Delete __init in include/linux/acpi.h for GTDT API Make ARM64 select GTDT. Delete "#include <linux/module.h>" from acpi_gtdt.c Simplify GT block parse code. v7: https://lkml.org/lkml/2016/7/13/769 Move the GTDT driver to drivers/acpi/arm64 Add add the ARM64-specific ACPI Support maintainers in MAINTAINERS Merge 3 patches of GTDT parser driver. Fix the for_each_platform_timer bug. v6: https://lkml.org/lkml/2016/6/29/580 split the GTDT driver to 4 parts: basic, arch_timer, memory-mapped timer, and SBSA Generic Watchdog timer Improve driver by suggestions and example code from Daniel Lezcano v5: https://lkml.org/lkml/2016/5/24/356 Sorting out all patches, simplify the API of GTDT driver: GTDT driver just fills the data struct for arm_arch_timer driver. v4: https://lists.linaro.org/pipermail/linaro-acpi/2016-March/006667.html Delete the kvm relevant patches Separate two patches for sorting out the code for arm_arch_timer. Improve irq info export code to allow missing irq info in GTDT table. v3: https://lkml.org/lkml/2016/2/1/658 Improve GTDT driver code: (1)improve pr_* by defining pr_fmt(fmt) (2)simplify gtdt_sbsa_gwdt_init (3)improve gtdt_arch_timer_data_init, if table is NULL, it will try to get GTDT table. Move enum ppi_nr to arm_arch_timer.h, and add enum spi_nr. Add arm_arch_timer get ppi from DT and GTDT support for kvm. v2: https://lkml.org/lkml/2015/12/2/10 Rebase to latest kernel version(4.4-rc3). Fix the bug about the config problem, use CONFIG_ACPI_GTDT instead of CONFIG_ACPI in arm_arch_timer.c v1: The first upstreaming version: https://lkml.org/lkml/2015/10/28/553 Fu Wei (9): clocksource/drivers/arm_arch_timer: Move enums and defines to header file clocksource/drivers/arm_arch_timer: Add a new enum for spi type clocksource/drivers/arm_arch_timer: Improve printk relevant code clocksource/drivers/arm_arch_timer: use readq to get 64-bit CNTVCT acpi/arm64: Add GTDT table parse driver clocksource/drivers/arm_arch_timer: Simplify ACPI support code. acpi/arm64: Add memory-mapped timer support in GTDT driver clocksource/drivers/arm_arch_timer: Add GTDT support for memory-mapped timer acpi/arm64: Add SBSA Generic Watchdog support in GTDT driver arch/arm64/Kconfig | 1 + drivers/acpi/Kconfig | 5 + drivers/acpi/Makefile | 1 + drivers/acpi/arm64/Kconfig | 5 + drivers/acpi/arm64/Makefile | 1 + drivers/acpi/arm64/acpi_gtdt.c | 309 +++++++++++++++++++++++++++++++++++ drivers/clocksource/Kconfig | 2 +- drivers/clocksource/arm_arch_timer.c | 233 +++++++++++++++++--------- drivers/watchdog/Kconfig | 1 + include/clocksource/arm_arch_timer.h | 32 ++++ include/linux/acpi.h | 7 + 11 files changed, 519 insertions(+), 78 deletions(-) create mode 100644 drivers/acpi/arm64/Kconfig create mode 100644 drivers/acpi/arm64/Makefile create mode 100644 drivers/acpi/arm64/acpi_gtdt.c -- 2.5.5

[PATCH v8 0/9] acpi, clocksource: add GTDT driver and GTDT support in arm_arch_timer

by fu.wei＠linaro.org

From: Fu Wei <fu.wei(a)linaro.org> This patchset: (1)Preparation for adding GTDT support in arm_arch_timer: 1. Move some enums and marcos to header file; 2. Add a new enum for spi type; 3. Improve printk relevant code; 4. use readq to get 64-bit CNTVCT. (2)Introduce ACPI GTDT parser: drivers/acpi/arm64/acpi_gtdt.c Parse all kinds of timer in GTDT table of ACPI:arch timer, memory-mapped timer and SBSA Generic Watchdog timer. This driver can help to simplify all the relevant timer drivers, and separate all the ACPI GTDT knowledge from them. (3)Simplify ACPI code for arm_arch_timer (4)Add GTDT support for ARM memory-mapped timer This patchset has been tested on the following platforms: (1)ARM Foundation v8 model Changelog: v8: https://lkml.org/lkml/2016/7/ Improve "pr_fmt(fmt)" definition: add "ACPI" in front of "GTDT", and also improve printk message.

[RFC PATCH v4 0/5] ECAM quirks handling for ARM64 platforms

by Tomasz Nowicki

Quirk handling relies on an idea of matching MCFG OEM ID, TABLE ID and revision (the ones from standard header of MCFG table). Static array is used to keep quirk entries. Each entry consist of metioned MCFG IDs along with custom pci_ops structure and initialization call. As an example, last patch presents quirk handling mechanism usage for ThunderX PEM driver.

[RESEND PATCH v5 0/1] ARM64: ACPI: Update documentation for latest specification version

by Al Stone

This is a resend only: Ping? Last ping was 26 May; there has been zero response since then. Already have one ACK from Lorenzo; another from an arm64 maintainer would be really helpful. The ACPI 6.1 specification was recently released at the end of January 2016, but the arm64 kernel documentation for the use of ACPI was written for the 5.1 version of the spec. There were significant additions to the spec that had not yet been mentioned -- for example, the 6.0 mechanisms added to make it easier to define processors and low power idle states, as well as the 6.1 addition allowing regular interrupts (not just from GPIO) be used to signal ACPI general purpose events. This patch reflects going back through and examining the specs in detail and updating content appropriately. Whilst there, a few odds and ends of typos were caught as well. This brings the documentation up to date with ACPI 6.1 for arm64. Changes for v5: -- Miscellaneous typos and corrections (Lorenzo Pieralisi) -- Add linux-acpi@ ML to the distribution list (Alexey Klimov) -- Corrections to CPPC information (Alexey Klimov) -- ACK from Lorenzo Pieralisi -- Updated bibliographic info (Al Stone) Changes for v4: -- Clarify that IORT can sometimes be optional (Jon Masters). -- Remove "Use as needed" descriptions of ACPI objects; they provide no substantive information and doing so simplifies maintenance of this document over time. These have been replaced with a simpler notice that states that unless otherwise noted, do what the ACPI specification says is needed. -- Corrected the _OSI object usage recommendation; it described kernel behavior that does not exist (Al Stone). Changes for v3: -- Clarify use of _LPI/_RDI (Vikas Sajjan) -- Whitespace cleanup as pointed out by checkpatch Changes for v2: -- Clean up white space (Harb Abdulhahmid) -- Clarification on _CCA usage (Harb Abdulhamid) -- IORT moved to required from recommended (Hanjun Guo) -- Clarify IORT description (Hanjun Guo) Al Stone (1): ARM64: ACPI: Update documentation for latest specification version Documentation/arm64/acpi_object_usage.txt | 343 ++++++++++++++++-------------- Documentation/arm64/arm-acpi.txt | 40 ++-- 2 files changed, 213 insertions(+), 170 deletions(-) -- 2.5.5

by fu.wei＠linaro.org

From: Fu Wei <fu.wei(a)linaro.org> This patchset: (1)Preparation for adding GTDT support in arm_arch_timer 1. Move some enums and marcos to header file 2. Add a new enum for spi type. 3. Improve printk relevant code (2)Introduce ACPI GTDT parser: drivers/acpi/gtdt.c Parse all kinds of timer in GTDT table of ACPI:arch timer, memory-mapped timer and SBSA Generic Watchdog timer. This driver can help to simplify all the relevant timer drivers, and separate all the ACPI GTDT knowledge from them. (3)Simplify ACPI code for arm_arch_timer (4)Add GTDT support for ARM memory-mapped timer This patchset has been tested on the following platforms: (1)ARM Foundation v8 model Changelog: v5: Sorting out all patches, simplify the API of GTDT driver: GTDT driver just fills the data struct for arm_arch_timer driver. v4: https://lists.linaro.org/pipermail/linaro-acpi/2016-March/006667.html Delete the kvm relevant patches Separate two patches for sorting out the code for arm_arch_timer.

[PATCH v5 0/1] ARM64: ACPI: Update documentation for latest specification version

by Al Stone

The ACPI 6.1 specification was recently released at the end of January 2016, but the arm64 kernel documentation for the use of ACPI was written for the 5.1 version of the spec. There were significant additions to the spec that had not yet been mentioned -- for example, the 6.0 mechanisms added to make it easier to define processors and low power idle states, as well as the 6.1 addition allowing regular interrupts (not just from GPIO) be used to signal ACPI general purpose events. This patch reflects going back through and examining the specs in detail and updating content appropriately. Whilst there, a few odds and ends of typos were caught as well. This brings the documentation up to date with ACPI 6.1 for arm64. Changes for v5: -- Miscellaneous typos and corrections (Lorenzo Pieralisi) -- Add linux-acpi@ ML to the distribution list (Alexey Klimov) -- Corrections to CPPC information (Alexey Klimov) -- ACK from Lorenzo Pieralisi -- Updated bibliographic info (Al Stone) Changes for v4: -- Clarify that IORT can sometimes be optional (Jon Masters). -- Remove "Use as needed" descriptions of ACPI objects; they provide no substantive information and doing so simplifies maintenance of this document over time. These have been replaced with a simpler notice that states that unless otherwise noted, do what the ACPI specification says is needed. -- Corrected the _OSI object usage recommendation; it described kernel behavior that does not exist (Al Stone). Changes for v3: -- Clarify use of _LPI/_RDI (Vikas Sajjan) -- Whitespace cleanup as pointed out by checkpatch Changes for v2: -- Clean up white space (Harb Abdulhahmid) -- Clarification on _CCA usage (Harb Abdulhamid) -- IORT moved to required from recommended (Hanjun Guo) -- Clarify IORT description (Hanjun Guo) Al Stone (1): ARM64: ACPI: Update documentation for latest specification version Documentation/arm64/acpi_object_usage.txt | 343 ++++++++++++++++-------------- Documentation/arm64/arm-acpi.txt | 40 ++-- 2 files changed, 213 insertions(+), 170 deletions(-) -- 2.5.5

[PATCH] Platforms/ARM: Juno: Update _PRT to provide interrupt type

by Punit Agrawal

The PCI Routing Table (_PRT) for Juno does not specify the Interrupt trigger type and polarity. In the absence of this information, the kernel uses PCI default interrupt type (level triggered, active low) which is incompatible with GICv2 compliant interrupt controller such as on Juno. Absence of interrupt type leads to errors such as following in kernel boot log - [ 1.353696] genirq: Setting trigger mode 8 for irq 9 failed (gic_set_type+0x0/0x5c) [ 1.478286] genirq: Setting trigger mode 8 for irq 17 failed (gic_set_type+0x0/0x5c) [ 1.563723] genirq: Setting trigger mode 8 for irq 18 failed (gic_set_type+0x0/0x5c) Fix this issue by providing the correct information (level triggered, active high) to the kernel by using the PCI Link device.

Additional ACPI requirements

by Jon Masters

Hi Folks, There are a few requirements that I would like to ensure are documented in various revised documentation. I'm curious to know whether you'd like the current in-kernel documentation to include things at the level of "GICv3 use requires that every processor have a Processor Device in the DSDT". Is that too much detail for the kernel documentation? Jon. -- Computer Architect | Sent from my Fedora powered laptop

[PATCH v4] ARM64: ACPI: Update documentation for latest specification version

by Al Stone

The ACPI 6.1 specification was recently released at the end of January 2016, but the arm64 kernel documentation for the use of ACPI was written for the 5.1 version of the spec. There were significant additions to the spec that had not yet been mentioned -- for example, the 6.0 mechanisms added to make it easier to define processors and low power idle states, as well as the 6.1 addition allowing regular interrupts (not just from GPIO) be used to signal ACPI general purpose events. This patch reflects going back through and examining the specs in detail and updating content appropriately. Whilst there, a few odds and ends of typos were caught as well. This brings the documentation up to date with ACPI 6.1 for arm64. Changes for v4: -- Clarify that IORT can sometimes be optional (Jon Masters). -- Remove "Use as needed" descriptions of ACPI objects; they provide no substantive information and doing so simplifies maintenance of this document over time. These have been replaced with a simpler notice that states that unless otherwise noted, do what the APCI specification says is needed. -- Corrected the _OSI object usage recommendation; it described kernel behavior that does not exist (Al Stone). Changes for v3: -- Clarify use of _LPI/_RDI (Vikas Sajjan) -- Whitespace cleanup as pointed out by checkpatch Changes for v2: -- Clean up white space (Harb Abdulhahmid) -- Clarification on _CCA usage (Harb Abdulhamid) -- IORT moved to required from recommended (Hanjun Guo) -- Clarify IORT description (Hanjun Guo) Signed-off-by: Al Stone <al.stone(a)linaro.org> Cc: Catalin Marinas <catalin.marinas(a)arm.com> Cc: Will Deacon <will.deacon(a)arm.com> Cc: Jonathan Corbet <corbet(a)lwn.net> --- Documentation/arm64/acpi_object_usage.txt | 347 ++++++++++++++++-------------- Documentation/arm64/arm-acpi.txt | 28 ++- 2 files changed, 212 insertions(+), 163 deletions(-) diff --git a/Documentation/arm64/acpi_object_usage.txt b/Documentation/arm64/acpi_object_usage.txt index a6e1a18..3891750 100644 --- a/Documentation/arm64/acpi_object_usage.txt +++ b/Documentation/arm64/acpi_object_usage.txt @@ -13,14 +13,18 @@ For ACPI on arm64, tables also fall into the following categories: -- Required: DSDT, FADT, GTDT, MADT, MCFG, RSDP, SPCR, XSDT - -- Recommended: BERT, EINJ, ERST, HEST, SSDT + -- Recommended: BERT, EINJ, ERST, HEST, PCCT, SSDT - -- Optional: BGRT, CPEP, CSRT, DRTM, ECDT, FACS, FPDT, MCHI, MPST, - MSCT, RASF, SBST, SLIT, SPMI, SRAT, TCPA, TPM2, UEFI + -- Optional: BGRT, CPEP, CSRT, DBG2, DRTM, ECDT, FACS, FPDT, MCHI, + MPST, MSCT, NFIT, PMTT, RASF, SBST, SLIT, SPMI, SRAT, STAO, TCPA, + TPM2, UEFI, XENV - -- Not supported: BOOT, DBG2, DBGP, DMAR, ETDT, HPET, IBFT, IVRS, - LPIT, MSDM, RSDT, SLIC, WAET, WDAT, WDRT, WPBT + -- Not supported: BOOT, DBGP, DMAR, ETDT, HPET, IBFT, IVRS, LPIT, + MSDM, OEMx, PSDT, RSDT, SLIC, WAET, WDAT, WDRT, WPBT + -- NB: the IORT is required on certain SBSA platforms (e.g., when + using GICv3-ITS and an SMMU); it is optional on SBSA Level 0 + platforms.

[PATCH v3] ARM64: ACPI: Update documentation for latest specification version

by Al Stone

The ACPI 6.1 specification was recently released at the end of January 2016, but the arm64 kernel documentation for the use of ACPI was written for the 5.1 version of the spec. There were significant additions to the spec that had not yet been mentioned -- for example, the 6.0 mechanisms added to make it easier to define processors and low power idle states, as well as the 6.1 addition allowing regular interrupts (not just from GPIO) be used to signal ACPI general purpose events. This patch reflects going back through and examining the specs in detail and updating content appropriately. Whilst there, a few odds and ends of typos were caught as well. This brings the documentation up to date with ACPI 6.1 for arm64. Changes for v3: -- Clarify use of _LPI/_RDI (Vikas Sajjan) -- Whitespace cleanup as pointed out by checkpatch Changes for v2: -- Clean up white space (Harb Abdulhahmid) -- Clarification on _CCA usage (Harb Abdulhamid) -- IORT moved to required from recommended (Hanjun Guo) -- Clarify IORT description (Hanjun Guo) Signed-off-by: Al Stone <al.stone(a)linaro.org> Cc: Catalin Marinas <catalin.marinas(a)arm.com> Cc: Will Deacon <will.deacon(a)arm.com> Cc: Jonathan Corbet <corbet(a)lwn.net> --- Documentation/arm64/acpi_object_usage.txt | 446 ++++++++++++++++++++++-------- Documentation/arm64/arm-acpi.txt | 28 +- 2 files changed, 357 insertions(+), 117 deletions(-) diff --git a/Documentation/arm64/acpi_object_usage.txt b/Documentation/arm64/acpi_object_usage.txt index a6e1a18..756d2f8 100644 --- a/Documentation/arm64/acpi_object_usage.txt +++ b/Documentation/arm64/acpi_object_usage.txt @@ -11,15 +11,16 @@ outside of the UEFI Forum (see Section 5.2.6 of the specification).

[PATCH v10] acpi, apei, arm64: APEI initial support for aarch64.

by fu.wei＠linaro.org

From: Tomasz Nowicki <tomasz.nowicki(a)linaro.org> This commit provides APEI arch-specific bits for aarch64 Meanwhile, (1)add a new subfunction "hest_ia32_init" for "acpi_disable_cmcff" which is used by IA-32 Architecture Corrected Machine Check (CMC).

[PATCH v2 0/4] ACPI based PCI host driver with generic ECAM

by Jayachandran C

Here is v2 of the patchset for the ACPI PCI controller driver based on the earlier discussion[1]. This patchset unifies the pci-host-generic ECAM code and the ACPI PCI ECAM code much further so that both the implementations can use the same structure (struct pci_config_window) as ->sysdata. The patchset should also make it easier to share platform quirks between DT and ACPI PCI controller drivers using struct pci_generic_ecam_ops. Short description of the patches in the patchset: - fixup arm64 PCI code so that it can use the generic ACPI PCI driver. - implement pci/drivers/ecam.[ch] which will replace drivers/pci/host/pci-host-common.h API for ECAM access and will be shared by ACPI and DT. - Update users of the pci-host-common API to the ecam API - implement a simple PCI ACPI host. I have not used the pci_mmcfg_list or the region definitions from x86, but have used a much simpler approach here. This should apply cleanly on top of the current 4.6 tree or the pci next tree, and can be reviewed as a patchset. The full set of changes for arm64 includes other fixes, that series is available at https://github.com/jchandra-brcm/linux branch arm64-acpi-pci-v2 This has been tested on qemu with OVMF for the ACPI part and with device tree for pci-host-generic code. Further testing and reviews are welcome. Thanks, JC.

[PATCH V5 00/15] MMCONFIG refactoring and support for ARM64 PCI hostbridge init based on ACPI

by Tomasz Nowicki

>From the functionality point of view this series might be split into the following logic parts: 1. Make MMCONFIG code arch-agnostic which allows all architectures to collect PCI config regions and used when necessary. 2. Move non-arch specific bits to the core code. 3. Use MMCONFIG code and implement generic ACPI based PCI host controller driver. 4. Enable above driver on ARM64 Patches has been built on top of 4.5-rc3 and can be found here: git@github.com:semihalf-nowicki-tomasz/linux.git (pci-acpi-v5) NOTE, this patch set depends on Lorenzo's fixes: https://patchwork.ozlabs.org/patch/576450/ which can be found in pci-acpi-v5 branch. This has been tested on Cavium ThunderX server, JunoR2, HP RX2660 IA64, x86, Hip05, X-Gene and QEMU-aarch64. Any help in reviewing and testing is very appreciated. v4 -> v5 - dropped MCFG refactoring group patches 1-6 from series v4 and integrated Jayachandran's patch https://patchwork.ozlabs.org/patch/575525/ - rewrite PCI legacy IRQs allocation - squashed two patches 11 and 12 from series v4, fixed bisection issue - changelog improvements - rebased to 4.5-rc3 v3 -> v4 - dropped Jiang's fix http://lkml.iu.edu/hypermail/linux/kernel/1601.1/04318.html - added Lorenzo's fix patch 19/24 - ACPI PCI bus domain number assigning cleanup - changed resource management, we now claim and reassign resources - improvements for applying quirks - dropped Matthew's http://www.spinics.net/lists/linux-pci/msg45950.html dependency - rebased to 4.5-rc1 v2 -> v3 - fix legacy IRQ assigning and IO ports registration - remove reference to arch specific companion device for ia64 - move ACPI PCI host controller driver to pci_root.c - drop generic domain assignment for x86 and ia64 as I am not able to run all necessary test variants - drop patch which cleaned legacy IRQ assignment since it belongs to Mathew's series: https://patchwork.ozlabs.org/patch/557504/ - extend MCFG quirk code - rebased to 4.4 v1 -> v2 - moved non-arch specific piece of code to dirver/acpi/ directory - fixed IO resource handling - introduced PCI config accessors quirks matching - moved ACPI_COMPANION_SET to generic code v1 - https://lkml.org/lkml/2015/10/27/504 v2 - https://lkml.org/lkml/2015/12/16/246 v3 - http://lkml.iu.edu/hypermail/linux/kernel/1601.1/04308.html v4 - https://lkml.org/lkml/2016/2/4/646 Jayachandran C (1): ACPI: MCFG: Move mmcfg_list management to drivers/acpi Lorenzo Pieralisi (1): drivers: pci: add generic code to claim bus resources Tomasz Nowicki (13): acpi, pci, mcfg: Provide default RAW ACPI PCI config space accessors. arm64, acpi: Use MCFG library and empty PCI config space accessors from pci_mcfg.c file. pci, acpi, ecam: Add flag to indicate whether ECAM region was hot added or not. x86, pci: Cleanup platform specific MCFG data by using ECAM hot_added flag. pci, acpi, x86, ia64: Move ACPI host bridge device companion assignment to core code. pci, acpi: Provide generic way to assign bus domain number. x86, ia64: Include acpi_pci_{add|remove}_bus to the default pcibios_{add|remove}_bus implementation. acpi, mcfg: Add default PCI config accessors implementation and initial support for related quirks. pci, of: Move the PCI I/O space management to PCI core code. pci, acpi: Support for ACPI based generic PCI host controller initialization pci, acpi: Match PCI config space accessors against platfrom specific quirks. arm64, pci, acpi: Assign legacy IRQs once device is enable. arm64, pci, acpi: Start using ACPI based PCI host bridge driver for ARM64. arch/arm64/Kconfig | 5 + arch/arm64/kernel/pci.c | 35 +--- arch/ia64/hp/common/sba_iommu.c | 2 +- arch/ia64/include/asm/pci.h | 1 - arch/ia64/pci/pci.c | 26 --- arch/ia64/sn/kernel/io_acpi_init.c | 4 +- arch/x86/include/asm/pci.h | 3 - arch/x86/include/asm/pci_x86.h | 24 +-- arch/x86/pci/acpi.c | 47 +---- arch/x86/pci/common.c | 10 - arch/x86/pci/mmconfig-shared.c | 269 ++++--------------------- arch/x86/pci/mmconfig_32.c | 1 + arch/x86/pci/mmconfig_64.c | 1 + arch/x86/pci/numachip.c | 1 + drivers/acpi/Kconfig | 7 + drivers/acpi/Makefile | 1 + drivers/acpi/pci_mcfg.c | 392 +++++++++++++++++++++++++++++++++++++ drivers/acpi/pci_root.c | 154 ++++++++++++++- drivers/of/address.c | 116 +---------- drivers/pci/pci.c | 126 +++++++++++- drivers/pci/probe.c | 5 + drivers/pci/setup-bus.c | 63 ++++++ drivers/xen/pci.c | 5 +- include/acpi/acpi_bus.h | 1 + include/asm-generic/vmlinux.lds.h | 7 + include/linux/of_address.h | 9 - include/linux/pci-acpi.h | 68 +++++++ include/linux/pci.h | 6 + 28 files changed, 892 insertions(+), 497 deletions(-) create mode 100644 drivers/acpi/pci_mcfg.c -- 1.9.1

[PATCH v8] acpi, apei, arm64: APEI initial support for aarch64.

by fu.wei＠linaro.org

From: Tomasz Nowicki <tomasz.nowicki(a)linaro.org> This commit provides APEI arch-specific bits for aarch64 Meanwhile, (1)add a new subfunction "hest_ia32_init" for "acpi_disable_cmcff" which is used by IA-32 Architecture Corrected Machine Check (CMC).

[PATCH] acpi: gtdt: Fix the wrong checking of GTDT block

by Vikas C Sajjan

when "fwts gtdt" is executed, fwts throws below error even when the GTDT table looks fine in the "fwts acpidump". gtdt: GTDT Generic Timer Description Table test ------------------------------- Test 1 of 1: GTDT Generic Timer Description Table test. FAILED [HIGH] GTDTShortBlock: Test 1, GTDT block is too short ------------------------------- This patch removes the error checking, since (ptr + 20) is always less than end_ptr even for the valid GTDT block.

[RESEND PATCH v4 0/5] acpi, clocksource: add GTDT and ARM memory-mapped timer support

by fu.wei＠linaro.org

From: Fu Wei <fu.wei(a)linaro.org> This patchset: (1)Move some enums and marcos to header file for arm_arch_timer, improve the pr_* code by defining "pr_fmt(fmt)" in arm_arch_timer.c (2)Introduce ACPI GTDT parser: drivers/acpi/gtdt.c Parse all kinds of timer in GTDT table of ACPI:arch timer, memory-mapped timer and SBSA Generic Watchdog timer. This driver can help to simplify all the relevant timer drivers, and separate all the ACPI GTDT knowledge from them. (3)Simplify ACPI code for arch timer in arm_arch_timer.c (4)Add memory-mapped timer support in arm_arch_timer.c RESEND: -- Corrected Cc list: added missing mailing lists Changelog: v4: https://lists.linaro.org/pipermail/linaro-acpi/2016-March/006667.html Delete the kvm relevant patches Separate two patches for sorting out the code for arm_arch_timer.
